Police officers use portable trace detection devices for a number of purposes, including screening seized banknotes or licensed premises for traces of controlled drugs. If those premises test positive for drug traces, the police could apply to have the landlord's license to sell alcohol revoked, on the grounds that they allowed those premises to be used for consumption of controlled drugs.
A public house where the police suspect the customers are habitually consuming controlled drugs is visited by police officers and areas within the premises are swabbed. Those swabs are screened for the presence of controlled drugs, using mobile drugs detection devices. The testing indicates that some of the areas tested within the premises are contaminated with traces of cocaine. The police use those results to apply for the alcohol license for the public house to be revoked.
Trace detection is an area of forensic drugs analysis which has to be carried out under stringent conditions as the tester is effectively analysing for invisible traces of drugs and inadvertent contamination of items is a real possibility. Our experts have years of experience of trace analysis and are well versed in the strict protocols that need to be followed to minimise or rule out the risk of inadvertent contamination during the testing process.
